Description

The *unit-transform* variable holds the list (1 0 0 1 0 0) which is the unit transform I, such that X = XI, where X is a 3-vector. Graphics ports are initialized with the unit transform in their graphics state. This means that port coordinate axes are initially the same as the window axes.
